Kubota KX040-5 Rubber Tracks & Parts

The Kubota KX040-5 runs a 350x54.5x86 track: 350 mm across the tread, 54.5 mm between links, 86 links around. Cut for digging, trenching, backfill and tight-quarters work and shipped free to the lower 48.

What the numbers mean on a Kubota KX040-5

  • 350x54.5x86 — 350 mm tread width (about 14"), 54.5 mm pitch, 86 links

Width is the tread face, pitch is the distance between drive lugs, and links is the count around the loop. All three have to match — a track one link off will not tension correctly no matter how close the width is.

Tread choice for the Kubota KX040-5

Size gets the track on the machine; tread decides how it works and how long it lasts. What we stock for this one:

  • Non-Directional — turf and finished surfaces. Minimal ground disturbance

How these wear

Excavator undercarriages load one side hard on slew and travel, so link cracking usually shows up before the tread wears out. Replace in pairs where you can: a new track running against a stretched one loads the drive unevenly and you will feel it in the steering.

Same track, other machines

Track size follows undercarriage geometry, not brand, so 350x54.5x86 shows up on machines from several makers. If you run any of these alongside the Kubota KX040-5, it is the same belt:

  • 100% Virgin Rubber

    Engineered to resist chunking, tearing, and cutting in harsh, abrasive environments.

  • Continuous Steel Cords

    Jointless internal cable architecture eliminates structural weak points and maximizes overall tensile strength.

  • Drop-Forged Links

    Precision heat-treated guide lugs ensure exact sprocket engagement and prevent de-tracking under heavy side-loads.

  • Corrosion Resistant

    The internal steel framework is fully encapsulated to prevent oxidation, rust, and moisture penetration.

  • Reinforced Sidewalls

    Extra-thick vulcanized rubber and tapered edge profiles protect against curb slashing and lateral impacts from jobsite debris.

  • Low-Vibration Tread

    Optimized lug spacing and pitch geometry absorb shock, reducing undercarriage wear and minimizing cabin vibration.

Does TrackTECH carry undercarriage parts for the Kubota KX040-5?
Yes. When a matched part is available, this Kubota KX040-5 hub can show the drive sprocket, front or rear idlers, and rollers alongside the tracks.
